Interleukin (IL)-1β-induced chondrocyte apoptosis is associated with the pathogenesis of arthritis. Platelet‑rich plasma (PRP), which is derived from the patient's own blood and contains numerous growth factors, has the potential for arthritis treatment. Therefore, the present study aimed to determine the effects of PRP on chondrocyte apoptosis, under IL‑1β‑induced pathological conditions. Chondrocytes isolated from the knee joint of Sprague Dawley rats were used in the present study. Cell viability was determined using the Cell Counting kit‑8 assay, cell apoptosis was evaluated by flow cytometry, and the expression of apoptosis‑, anabolism‑ and catabolism-associated genes were detected by quantitative polymerase chain reaction; protein expression was detected by western blot analysis...

Osteoarthritis (OA) is a degenerative disorder resulting from loss of joint cartilage and underlying bone and causes pain and loss of function. The treatment of knee OA is still a challenge because of the poor self-regeneration capacity of cartilage. The nonsurgical interventions include control of the aggravating factor (such as weight control and the use of walking aids), symptomatic treatment (such as acetaminophen or nonsteroidal anti-inflammatory drugs), prolotherapy, and viscosupplementation. However, the combination of platelet-rich plasma (PRP) and hyaluronic acid (HA) has not been widely used because of lack of clinical evidence and several limitations in patients with severe knee OA...

INTRODUCTION: Knee osteoarthritis (OA) is a degenerative and progressive articular cartilage disease. Infiltration of autologous platelet-rich plasma (PRP) has been proposed as a therapeutic alternative due to the content of biologically active cytokines in PRP. We aimed to compare the clinical response of acetaminophen and intra-articular leukocyte-poor PRP (LP-PRP) in early knee OA. MATERIALS AND METHODS: A total of 65 patients with clinically and radiographically documented knee OA (grade 1-2) were analyzed...

BACKGROUND: Recent studies have shown evidence that higher adiposity in the infrapatellar fat pad (IFP) induces inflammatory phenotypes in the knee joint and thereby contributes to the development and progression of osteoarthritis (OA). In particular, IFP adipocyte-derived inflammatory cytokines participate in pathological events. Our previous research has already addressed the therapeutic efficacy of hyaluronic acid and platelet-rich plasma (HA+PRP), including the promotion of cartilage regeneration and the inhibition of inflammation...

A bucket handle meniscal tear (BHMT) often causes intermittent locking of the affected knee as the displaced fragment flips into the intercondylar notch. Surgical correction is usually required. Rare spontaneous healing of BHMTs has been described, primarily in young patients. This case report describes a 43-year-old man with magnetic resonance imaging-confirmed medial BHMT who received 3 treatments of platelet-rich plasma injections in and around the meniscus within 7 months after the diagnosis of the tear...
